It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

The following described exemplary embodiments provide a system, method and program product for data pipeline prioritization. As such, the present embodiment has the capacity to improve the technical field of information management by utilizing a machine learning algorithm to prioritize data pipelines being run on a data lake. The present embodiment may automatically assign priorities to incoming data pipelines based on who is expected to consume the results of the pipeline, who triggered the pipeline, the overall resources needed to run the job, and/or when the job needs to be triggered based on a service level agreement (SLA) for the job. This information may be received through a data governance catalog, such as IBM's InfoSphere® Information Governance Catalog (InfoSphere and all InfoSphere-based trademarks are trademarks or registered trademarks of International Business Machines Corporation in the United States, and/or other countries), among other catalogs which enable users to understand and analyze information.

The machine learning algorithm may be trained on previous job runs, an analysis of dependencies on other pipelines, resource consumption data, and historical priorities.

More specifically, the present invention may include receiving, by a cognitive rules engine, one or more data pipelines. The present invention may then include analyzing, using a computational method of the cognitive rules engine, the one or more data pipelines. The present invention may lastly include prioritizing the one or more data pipelines based on a result of the computational method of the cognitive rules engine.

As described previously, a pipeline (i.e., a data pipeline, a job) may be used for feeding a data repository (e.g., a data lake) where data may be moved, transformed and loaded for data analytics, ad hoc investigations, and/or reporting, among other things. When triggered, a data pipeline may be run on a first come, first served basis.

The scheduling of a data pipeline may not consider that one data pipeline may be more critical than another; that the criticality of a data pipeline may change over a period of time; that a non-resource consuming data pipeline may be scheduled quickly; that there may be one or more service level agreements (SLAs) directing the execution of a data pipeline; or that a data pipeline may be feeding data to a critical pipeline, thereby making the data pipeline critical. Additionally, if the priority of a data pipeline is dynamic, then predicting when a given data pipeline is scheduled and finished may not be possible.

Therefore, it may be advantageous to, among other things, prioritize data pipelines by using a machine learning algorithm to automatically assign an appropriate priority level based on a set of metrics.

According to at least one embodiment, the present invention may utilize a data pipeline prioritization scheme, since resources used for analytics may be limited, and the analysis and reporting may require a time bound result.

According to at least one embodiment of the present invention, a machine learning algorithm may be utilized to reconcile the factors which may influence a data pipeline prioritization scheme. A machine learning algorithm may also be effective at handling large-scale data, including but not limited to sorting and evaluating data (e.g., recognizing the importance of a given job).

According to at least one embodiment of the present invention, information governance and machine learning may be utilized to make a scheduling decision. For example, a data governance catalog, such as IBM's InfoSphere® Information Governance Catalog (InfoSphere and all InfoSphere-based trademarks are trademarks or registered trademarks of International Business Machines Corporation in the United States, and/or other countries), among other catalogs, may be used to assign priorities to incoming data pipelines based on who is expected to consume the results of the data pipeline, who triggered the data pipeline, the overall resources needed to run the data pipeline (i.e., the job), and/or when the data pipeline (i.e., the job) needs to be triggered based on a service level agreement (SLA) for the data pipeline, among other things.

According to at least one embodiment of the present invention, automatic intelligence may be utilized to improve or enhance the schedule of work flows (i.e., data pipelines) as compared with known schedules of work flows.

According to at least one embodiment of the present invention, a machine learning algorithm may learn to prioritize certain data pipelines over others (e.g., to optimize a workload), based on learned metrics, including but not limited to metadata and consuming pipelines.

According to at least one embodiment of the present invention, a data pipeline (i.e., a job) may be transformed and moved to a data lake for analytics. The machine learning algorithm may then determine a priority of scheduling the data pipeline, and based on the determined priority, the jobs may be executed.

According to at least one embodiment of the present invention, information governance may be utilized to assign weights to a data pipeline. This may include giving consideration to which user may have triggered the data pipeline and/or which user may be awaiting a result of the data pipeline.

Referring to FIG. 1, an exemplary networked computer environment 100 in accordance with one embodiment is depicted. The networked computer environment 100 may include a computer 102 with a processor 104 and a data storage device 106 that is enabled to run a software program 108 and a data pipeline prioritization program 110 a. The networked computer environment 100 may also include a server 112 that is enabled to run a data pipeline prioritization program 110 b that may interact with a database 114 and a communication network 116. The networked computer environment 100 may include a plurality of computers 102 and servers 112, only one of which is shown. The communication network 116 may include various types of communication networks, such as a wide area network (WAN), local area network (LAN), a telecommunication network, a wireless network, a public switched network and/or a satellite network. It should be appreciated that FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

The client computer 102 may communicate with the server computer 112 via the communications network 116. The communications network 116 may include connections, such as wire, wireless communication links, or fiber optic cables. As will be discussed with reference to FIG. 4, server computer 112 may include internal components 902 a and external components 904 a, respectively, and client computer 102 may include internal components 902 b and external components 904 b, respectively. Server computer 112 may also operate in a cloud computing service model, such as Software as a Service (SaaS), Platform as a Service (PaaS), or Infrastructure as a Service (IaaS). Server 112 may also be located in a cloud computing deployment model, such as a private cloud, community cloud, public cloud, or hybrid cloud. Client computer 102 may be, for example, a mobile device, a telephone, a personal digital assistant, a netbook, a laptop computer, a tablet computer, a desktop computer, or any type of computing devices capable of running a program, accessing a network, and accessing a database 114. According to various implementations of the present embodiment, the data pipeline prioritization program 110 a, 110 b may interact with a database 114 that may be embedded in various storage devices, such as, but not limited to a computer/mobile device 102, a networked server 112, or a cloud storage service.

According to the present embodiment, a user using a client computer 102 or a server computer 112 may use the data pipeline prioritization program 110 a, 110 b (respectively) to utilize a machine learning algorithm to prioritize data pipelines being run on a data lake. The present embodiment may automatically assign priorities to incoming data pipelines based on who is expected to consume the results of the data pipeline, the overall resources needed to run the job, and/or when the job needs to be triggered based on a service level agreement (SLA) for the job. The machine learning algorithm may be trained on previous job runs, an analysis of dependencies on other pipelines, resource consumption data, and historical priorities. The data pipeline prioritization method is explained in more detail below with respect to FIGS. 2 and 3.

Referring now to FIG. 2, an operational flowchart illustrating the exemplary data pipeline prioritization process 200 used by the data pipeline prioritization program 110 a and 110 b according to at least one embodiment is depicted.

At 202, the data pipeline is submitted to a cognitive rules engine. A data pipeline (i.e., a job) may be transformed and moved to a data lake (e.g., a data repository) for analytics. A data pipeline may load from and/or feed into a data lake. A priority of scheduling for the data pipeline may be determined while data is loaded in the data lake, and the data pipeline may be executed based on the determined priority.

A data pipeline may be a set of data processing elements which may be connected in a series, wherein the output of one data element is the input to the next data element. The elements of a data pipeline may be executed in parallel or in a time-sliced manner. A data pipeline may be a continuous movement of instruction to the processor or in the steps taken by the processor to perform a given action.

For example, one or more data pipelines may be used to transfer data from a daily transactional database (e.g., a bank's database), wherein analytics may not be run, to a cloud server or data warehouse where the data may be stored for analytics and archival purposes. The one or more data pipelines may be used for the transfer of data from the daily transactional database to the data warehouse or cloud server, and while in the data warehouse or cloud server, an analysis of the data may be performed.

A machine learning algorithm (e.g., a neural network, among other machine learning algorithms) may be used by the cognitive rules engine to determine the priority of a data pipeline (i.e., a job), among various competing data pipelines, without using explicit instructions, and instead relying on models and inference to make a determination. A machine learning algorithm may utilize computational methods to perform data analytics and to learn information from a set of data. The learned information may be used to create a model which may then be used to analyze future sets of data. The model (i.e., the analytical model) created based on the learned information may describe relationships among variables in the data. The model may estimate and/or classify new data based on the new data's proximity (e.g., relatedness) to the created model. The quality of the machine learning model may be improved with an increase in available data.

The data pipeline prioritization program 110 a, 110 b may utilize a machine learning algorithm to derive the priority of a data pipeline (i.e., a job), among various competing data pipelines.

The machine learning algorithm used by the data pipeline prioritization program 110 a, 110 b may be a component of the cognitive rules engine, described in more detail with respect to step 204 below.

At 204, the cognitive rules engine determines a priority of a data pipeline (i.e., a job) based on a series of learned metrics. The learned metrics (i.e., computational methods) may comprise a machine learning algorithm of the cognitive rules engine. The learned metrics may take into account factors such as the existence of a service level agreement (SLA), specific user information, and server load, among other factors. The machine learning algorithm may learn from the factors and information, including those described above, and may use the learned factors and information to create a machine learning model. The machine learning model may be fine-tuned (e.g., a model created by the machine learning algorithm may be improved upon) based on information such as a missed SLA, or an overloaded server, among other information. The data pipeline prioritization program 110 a, 110 b may thereafter use the machine learning model to determine a priority of a data pipeline (i.e., a job).

The learned metrics may include factors which influence the performance of an executing server and/or whether a result of a data pipeline (i.e., a job) will be consumed by another user, among other factors which influence the determination of priority of a data pipeline (i.e., a job). To learn the metrics which influence the determination of the priority of a data pipeline (i.e., a job), the cognitive rules engine of the data pipeline prioritization program 110 a, 110 b may, for example, perform a result consumption analysis to predict who may consume the result, and a resource consumption analysis to predict the resources which may be required to run the data pipeline (i.e., a job).

The cognitive rules engine may also predict the amount of time that it will take for the data pipeline (i.e., a job) to be run, and when the data pipeline (i.e., a job) may need to be started and ended in order to meet a service level agreement (SLA). This prediction may include an analysis of all data pipelines (i.e., a jobs) and may give consideration to any data pipelines (i.e., a jobs) of higher priority which may need to be added in (e.g., executed out of order by an executing server).

The cognitive rules engine may also predict when the executing servers may be available to run a given data pipeline (i.e., a job), based on the current data pipeline (i.e., a job) execution order.

A prioritization prediction may also be based on a failure of the data pipeline data pipeline (i.e., a job), including an SLA being missed and/or a server being overloaded, among other things. In the event of noted failures, the data pipeline prioritization program 110 a, 110 b may opt to assign a more or less aggressive priority, based on a preconfigured preference of a user. The user may also be given the opportunity to manually enter a priority of a data pipeline (i.e., a job), in the event of a noted failure and/or based on various options of the data pipeline prioritization program 110 a, 110 b, including who triggered a given data pipeline (i.e., a job), and what reports the data pipeline (i.e., a job) feeds into, among other options. An enterprise user may, by virtue of the user's experience, know which data pipeline (i.e., job) should be given priority.

For example, the machine learning algorithm may be trained by providing to the user a list of who triggered particular data pipelines (i.e., jobs) and/or a list of reports that the data pipeline (i.e., the job) feeds into, based on a preference of the user. A random weight may be assigned for each criterion upon which a prioritization determination may be made. The machine learning algorithm may then correct the weights based on the learned metrics. Alternatively, a machine learning algorithm may learn from a manual priority assignment and begin assigning weights accordingly.

The cognitive rules engine may compute the priority of a data pipeline (i.e., a job) by aggregating the above factors, among other factors affecting the priority of a data pipeline (i.e., a job), to determine a data pipeline's (i.e., a job's) final priority score. Prior to determining a final priority score, each of the factors may be multiplied by a weight corresponding to the importance of the factor. The weight of a single factor may not be the same as the weight of a second factor. The weight of a single factor may also not be determinative of a final priority score. A factor's weight may be influenced by the priority given to the factor by a user of the data pipeline prioritization program 110 a, 110 b (e.g., by a manual weight assignment). A factor's weight may also be based on initial predefined knowledge (e.g., manual weight assignments) which are used to teach the machine learning algorithm. A factor's weight may ultimately be assigned automatically by the machine learning algorithm based on prior weights.

Further, the weight of a data pipeline (i.e., a job) may not be static. For example, when an SLA provides that a data pipeline (i.e., a job) should be finished within a one-week time frame, the data pipeline (i.e., the job) may be given a low priority. Thereafter, while the data pipeline (i.e., the job) is in the list of data pipelines approaching execution, the priority may begin to improve to meet a service level agreement, and the data pipeline (i.e., the job) may dynamically be given a higher priority.

As described above, a predictive (i.e., trained) model generated by the machine learning algorithm of the cognitive rules engine may predict a result consumption, criticality of a job (i.e., data pipeline), job dependency, job trigger(s), job SLA, and/or resource(s) required by a job, among other things. For each new job, the predictive model may use the generated predictions to rank the job and determine when the ranked job should be executed.

The resulting job (i.e., data pipeline) rank and priority, determined by the machine learning algorithm, may be utilized by the cognitive rules engine in determining an order of priority for the jobs ready for execution.

The predictive model may be retrained at a predetermined interval (e.g., at a daily, weekly, or monthly interval, among other intervals) or upon the completion of a data pipeline (i.e., a job). The predictive model may also be retrained based on user or system feedback (e.g., a service level agreement was missed and may thereafter be given a higher priority).

If the data pipeline is empty or requires minimal resources based on a previous run heuristic, information which may be determined (e.g., learned) by the data pipeline prioritization program 110 a, 110 b by utilizing results of the machine learning algorithm described in detail with respect to step 202 above, then the data pipeline may be executed without a reprioritization of the data pipelines (i.e., the jobs) (e.g., without any determination of priority by the data pipeline prioritization program 110 a, 110 b, based on the series of learned metrics previously described).

At 206, the data pipeline is reprioritized based on the determined priority at 204. A prioritization of jobs (i.e., data pipelines) determined by the data pipeline prioritization program 110 a, 110 b, based on the data analytics performed while the data pipeline was located within the data lake (i.e., the data repository), the machine learning algorithm may determine a priority of scheduling for the data pipeline (i.e., the job). Based on the determined priority, the data pipeline may be executed.

As described previously with respect to step 204 above, the data pipeline prioritization program 110 a, 110 b may dynamically reprioritize the data pipeline (i.e., the job) based on the dynamic weight assignments of factors affecting the priority of a data pipeline (i.e., a job).

Further, as described previously with respect to step 202 above, the data pipeline may be executed based on the determined priority. In an embodiment, two or more data pipelines may be run in parallel, and data may be partitioned within each of the parallel workflows. If the determined priority of a single data pipeline is less than a second data pipeline, then the amount of parallelism may be reduced (e.g., to one), and the throughput may be better than running multiple data pipelines. In this instance, there may be no need to repartition a set of data.

Conversely, if the determined priority of a single data pipeline is greater than a second data pipeline, then the flow of the data pipelines may be slowed down for the data pipeline with a lower priority, and the parallelism of the data pipeline with the greater priority may increase.

Referring now to FIG. 3, a block diagram of the cognitive rules engine according to at least one embodiment is depicted.

A result consumption analysis module 302 may refer to the number of consumers of a given result. The priority of a job (i.e., a data pipeline) may be increased as the number of consumers for a job result increases. For example, if the results of a previous pipeline are never consumed, then the data pipeline may be given a low priority. Conversely, if the number of consumers of a job is very high, then the priority of the job may be increased. The priority of a job may be proportionately increased as the number of consumers for the job increases.

The priority of a job (i.e., a data pipeline) may also increase if the consumers of the job are more important than others. For example, if the consumer of a job is a corporation's director who may be preparing for a board meeting, the priority of the job may increase. Similarly, if the consumer of the job is a free user of a computer program who may be running tests, the job may be given a low priority.

A dependency analysis module 304 may refer to whether the result of a current job (i.e., a data pipeline) is used by another job. If the result of a current job is used by another (e.g., a second) job, then the priority of the job may increase. The priority of a current job may be dictated by the priority of the jobs which depend on it. For example, if pipeline “A” modifies the input to pipeline “B,” then the priority of pipeline “A” may increase if the priority of pipeline “B” is greater than the priority of pipeline “A.” The dependency of jobs may be determined based on metadata, which may be a set of data that describes the jobs. Metadata may be gathered from IBM's InfoSphere® Information Governance Catalog (InfoSphere and all InfoSphere-based trademarks are trademarks or registered trademarks of International Business Machines Corporation in the United States, and/or other countries), among other catalogs.

A governance catalog (i.e., an information governance catalog) used by the data pipeline prioritization program 110, 110 b may be a catalog of data which may assist in determining a priority of a data pipeline. A governance catalog may, for example, map and/or store business information to technical information. The business information and/or associated metadata may include users of a set of data, and time of use of a set of data, among many other points of business information which may be critical to the determination of priority of a job (i.e., a data pipeline).

An estimation of job start time module 306 may refer to a machine learning analysis of available bandwidth of an executing server (i.e., a server, a consumption resource) at a given time, and may take into consideration any service level agreements (SLAs). For example, if an agreed upon job (i.e., data pipeline) in a service level agreement (SLA) is to complete within twelve hours, based on a machine learning analysis of the job's start time and the usual load of servers at the job's start time, and if it was agreed upon that the job in the SLA would complete within eight hours, then the data pipeline prioritization program 110 a, 110 b may increase the priority of the job in order to reduce the job's completion time, based on the agreed upon SLA.

An estimation of job start time may include an analysis of the time required to finish a job in order to meet an SLA.

This analysis may also include, but is not limited to including, information such as the availability of computational resources from the resource analysis consumption module 308, as described in more detail below.

A resource consumption analysis module 308 may refer to an analysis of the number of computational resources (i.e., executing servers) required to complete a job (i.e., a data pipeline). This analysis may include whether the job may require fewer or additional computational resources. If a job may be completed with fewer resources, then the data pipeline prioritization program 110 a, 110 b may reprioritize the job so that fewer resources may be utilized, as the job may not be competing with other jobs. The data pipeline prioritization program 110 a, 110 b may further determine that additional jobs may be scheduled (e.g., based on freeing up available resources).

Prior to scheduling a data pipeline (i.e., a job), the data pipeline prioritization program 110 a, 110 b may check whether any required computational resources are available. The data pipeline prioritization program 110 a, 110 b may determine a current priority based on an assigned historical priority. Historical usage data may be determined based on information stored within, or accessed by, the data pipeline prioritization program 110 a, 110 b.

For example, if a data pipeline (i.e., a job) follows the extract, load, and transform (ELT) data processing approach, this may mean that data is first extracted from the pipeline, loaded into a target database, and transformed and integrated into a desired format. The transformation processing in an ELT pipeline may take place within the target database, requiring little to no additional resources. In this case, the resource consumption analysis may reveal that since fewer resources are required for the handling of the ELT pipeline, more pipelines can be scheduled simultaneously with the ELT pipeline. That is to say that the ELT pipeline may be given a higher priority as it may not be competing for resources with other data pipelines.

A user consumption analysis module 310 may refer to an analysis of which users may be waiting for the results of the data pipeline (i.e., the job). A data pipeline may become more critical (i.e., may be given a higher priority) depending on the user or users waiting for the outcome. User consumption information may be gathered from IBM's InfoSphere® Information Governance Catalog (InfoSphere and all InfoSphere-based trademarks are trademarks or registered trademarks of International Business Machines Corporation in the United States, and/or other countries). For example, a paid user may be given a higher priority than a free user, and a corporation's data steward may be given a lower priority than the corporation's chief technology officer.

A historical priority module 312 may refer to an analysis of the priority given to a job (i.e., a data pipeline) or to a similar job, or to a job with similar characteristics. This analysis may take into consideration any user provided (i.e., manual) priority entries of a given job. An analysis of historical priority may be useful in assigning weights to a similar job.

It may be appreciated that FIGS. 2 and 3 provide only an illustration of one embodiment and do not imply any limitations with regard to how different embodiments may be implemented. Many modifications to the depicted embodiment(s) may be made based on design and implementation requirements.

According to at least one alternate embodiment of the present invention, a manual input of priority by a user of the data pipeline prioritization program 110 a, 110 b may be used in the place of a machine learning algorithm to generate a prioritization scheme for a data pipeline.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

-   -   On-demand self-service: a cloud consumer can unilaterally         provision computing capabilities, such as server time and         network storage, as needed automatically without requiring human         interaction with the service's provider.     -   Broad network access: capabilities are available over a network         and accessed through standard mechanisms that promote use by         heterogeneous thin or thick client platforms (e.g., mobile         phones, laptops, and PDAs).     -   Resource pooling: the provider's computing resources are pooled         to serve multiple consumers using a multi-tenant model, with         different physical and virtual resources dynamically assigned         and reassigned according to demand. There is a sense of location         independence in that the consumer generally has no control or         knowledge over the exact location of the provided resources but         may be able to specify location at a higher level of abstraction         (e.g., country, state, or datacenter).     -   Rapid elasticity: capabilities can be rapidly and elastically         provisioned, in some cases automatically, to quickly scale out         and rapidly released to quickly scale in. To the consumer, the         capabilities available for provisioning often appear to be         unlimited and can be purchased in any quantity at any time.     -   Measured service: cloud systems automatically control and         optimize resource use by leveraging a metering capability at         some level of abstraction appropriate to the type of service         (e.g., storage, processing, bandwidth, and active user         accounts). Resource usage can be monitored, controlled, and         reported providing transparency for both the provider and         consumer of the utilized service.

Service Models are as follows:

-   -   Software as a Service (SaaS): the capability provided to the         consumer is to use the provider's applications running on a         cloud infrastructure. The applications are accessible from         various client devices through a thin client interface such as a         web browser (e.g., web-based e-mail). The consumer does not         manage or control the underlying cloud infrastructure including         network, servers, operating systems, storage, or even individual         application capabilities, with the possible exception of limited         user-specific application configuration settings.     -   Platform as a Service (PaaS): the capability provided to the         consumer is to deploy onto the cloud infrastructure         consumer-created or acquired applications created using         programming languages and tools supported by the provider. The         consumer does not manage or control the underlying cloud         infrastructure including networks, servers, operating systems,         or storage, but has control over the deployed applications and         possibly application hosting environment configurations.     -   Infrastructure as a Service (IaaS): the capability provided to         the consumer is to provision processing, storage, networks, and         other fundamental computing resources where the consumer is able         to deploy and run arbitrary software, which can include         operating systems and applications. The consumer does not manage         or control the underlying cloud infrastructure but has control         over operating systems, storage, deployed applications, and         possibly limited control of select networking components (e.g.,         host firewalls).

Deployment Models are as follows:

-   -   Private cloud: the cloud infrastructure is operated solely for         an organization. It may be managed by the organization or a         third party and may exist on-premises or off-premises.     -   Community cloud: the cloud infrastructure is shared by several         organizations and supports a specific community that has shared         concerns (e.g., mission, security requirements, policy, and         compliance considerations). It may be managed by the         organizations or a third party and may exist on-premises or         off-premises.     -   Public cloud: the cloud infrastructure is made available to the         general public or a large industry group and is owned by an         organization selling cloud services.     -   Hybrid cloud: the cloud infrastructure is a composition of two         or more clouds (private, community, or public) that remain         unique entities but are bound together by standardized or         proprietary technology that enables data and application         portability (e.g., cloud bursting for load-balancing between         clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 5, illustrative cloud computing environment 1000 is depicted. As shown, cloud computing environment 1000 comprises one or more cloud computing nodes 100 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 1000A, desktop computer 1000B, laptop computer 1000C, and/or automobile computer system 1000N may communicate. Nodes 100 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 1000 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 1000A-N shown in FIG. 5 are intended to be illustrative only and that computing nodes 100 and cloud computing environment 1000 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 6, a set of functional abstraction layers 1100 provided by cloud computing environment 1000 is shown.
